About Compress PDF to 100KB

Compress PDF to Size makes your PDF fit an exact file size, such as 100KB, 200KB or 500KB. You set the target and the tool works to bring the file under it. It runs inside your browser, so your document is never uploaded. It is free, needs no sign-up and adds no watermark.

Many online forms reject files that are too big. Visa portals, job sites, university admissions and government forms in Pakistan and the Gulf often set strict limits. Use this tool for your CNIC, Iqama, degree or bank letter so the upload goes through the first time.
